The flags affect different things depending on the flag and the partition 
scheme used. For example the 'boot' flag on an MBR disk sets the status field 
byte for a partition from inactive/invalid to active, or "enabling the boot 
flag" in vernacular; whereas on a GPT disk, this same flag changes the 
partition type GUID field for a partition to 
C12A7328-F81F-11D2-BA4B-00A0C93EC93B, which is the code for "EFI System 

'raid' on MBR sets the partition type code to FDh. 'lvm' sets it to 8Eh.

So the flags are parted flags. They are not necessarily partition scheme flags.
